Its not ok to include multiple versions of a library in the main build. If a component needs another incompatible version is needs to be pulled out the build and integrated as a binary component with its conflicting version isolated via class loader scoping. If the error is due to changes in the commons httpclient, what are the changes causing problems? Updating the testsuite would make it incompatible with the 4.0 branch code.
